Man people really set up the strawmen here. Congress has literally said it’s about foreign influence, not about protecting children. It has absolutely nothing to do with kids. It has to do with China influencing the citizens of the United States to do things that are beneficial to China, against the interests of the US government.
It’s not a ban, if China gives up control of the app to a United States entity then there’s no problem. It has absolutely nothing to do with protecting children.
